I bought this recently for my WWII Arriflex 35, as they are in similar condition. However the lens protrudes too much at the back, and would foul the mirror shutter. The glass is very good, no fungus, or scratches that I can see. But the front ring has many signs of use, see pictures. A few tiny screws seem to be missing on close inspection. Focus is smooth, and f stops click well. I would have been happy with it if it had fitted my camera. I believe it must be for a 16mm Arriflex with a standard mount. Non original back and front caps included.
